Which apps are best for combined bets an

Which apps are best for combined bets and express bets? I'm interested in it being as convenient as possible and without confusing forms.

I like to collect express bets - 3-5 matches, sometimes more. The bookmaker 1xbet has everything for this: a convenient bet calculator right in the coupon, you can edit and recalculate on the go, plus the platform does not glitch when making large chains. I use both the mobile and web versions and everything works great. And which bookmaker do you use?
